I get this a fair bit Peter. It is the shutter and it is to do with power from the USB's as far as I can tell. I regularly unplug the USB cable and reseat it just to get rid of any contact dirt etc. That seems to fix it for a while until the next time it does it again. I found with a MHP it would do it all the time with the shutter showing just the barest of a slit. That was unworkable in the end for remote operation.
